The supply and output of natural construction sand along the Yangtze River has decreased. The main reason is that the local government has strengthened the management of yellow sand, and the existing mining sites have been reasonably controlled. New brick factories will not be approved to build yellow sand mining sites along the river. The principle of non-permission is regulated.
Mid-April 2018. Prices in most parts of the country are relatively stable, but there is a phenomenon of rising to a certain extent in some areas.
Machine-made sand and gravel in Yichang, Hubei rose by 5 yuan. Huangshi machine-made sand rose by about 2 yuan. Natural sand in Guangzhou, Guangdong rose by 10 yuan. The price of machine-made sand and gravel in Handan, Hebei was slightly raised. Stones in Luliang, Shanxi fell by 7 yuan. Natural sand in Shanghai rose by 5-8 yuan, and machine-made sand rose by 10 yuan.
On April 9, Ma Xingrui, Governor of Guangdong Province, revealed at the "Guangdong-Hong Kong-Macao Greater Bay Area" sub-forum that the plan for the Guangdong-Hong Kong-Macao Greater Bay Area will be released soon. During this period, the nine cities in Guangdong, which are about to enter the construction of the Greater Bay Area, are currently experiencing a situation of skyrocketing construction sand prices, and some areas have experienced four consecutive rounds of increases.
The aggregate of sand and gravel has shown an overall upward trend. As an excellent building material, machine-made sand has an irreplaceable position of desalinated sand and river sand. Production target, Bellian Machinery launched a new type of HVI environmental protection Sand Making Machine, which has the following functions.
Special design, high efficiency crushing
The impeller structure adopts a deep cavity four-port design, which increases the material throughput by more than 30%, and effectively improves the crushing efficiency. The advanced design of the bulk material tray can realize the rapid conversion of center feeding and cascading feeding, effectively reducing downtime and adjustment time, and improving work efficiency.
New design, extended life
Compared with the traditional integral design of the perimeter guard, it adopts a new combined design of the upper and lower perimeter guards. After partial wear, the head can be adjusted up and down for use, which greatly improves the utilization rate of materials and prolongs the service life.
Process upgrade, cost reduction
The throwing head technology is upgraded, and the upper and lower combined design is adopted. Only the worn part of the throwing head needs to be replaced, which can effectively prevent the vertical plate from being damaged after wear and tear. Compared with the old equipment, the cost of use can save two-thirds of the financial resources.
Modular design, optional lubrication method
Break the traditional design in the lubrication method, adopt the world's advanced modular design of thin oil type and grease type in the bearing chamber, which can realize the overall interchangeability, according to different needs, you can choose different lubrication methods, and replace it every 3-6 months Just lubricating oil, simple operation and convenient maintenance.
The key parts of the HVI impact sand making machine are all made of alloy materials. This equipment is especially suitable for providing high-quality sand and gravel aggregates in many fields such as high-rise buildings, road construction, municipal engineering, large-scale water conservancy facilities, and concrete mixing stations. It is the production mechanism. Good choice of sand.
